' ANCHOR-PLATE,

Specification of Letters Patent. Patented Dem 17 191 2 Application filed August 22, 1910. Serial No.- 578,414.

To all whom it may concern Be it known that I, HARRY ANsoHU'rz'. a citizen of the United States,'and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new anduseful Improvements in Anchor-Plates," of

which the following is a specification.

This invention relates to. anchor plates for connecting screw studs, bolts, and the like, to'the ends of hollow members.

i The object of the invention is to provide an anchor plate for this purpose, which willn I and claimed of a blank; adaptedfor making the form of" anchor. plate shown in- Figs; land 2 and Fig. i'is a view similar to Big. 2, showingthe anchor plate and hollow member as be eifective for its designed purpose, strong,

rigid and durable, and which can be produced at small cost.

.Tothis end an anchor plate of my inven tion comprises the various features and details of construction hereinafter describe In the accompanying drawing, in which my invention is fully illustrated, Figu're l is a side'view of an anchor plate of my invention, shown as applied for securing a cap orhead to a hollow member, bothin- 'dicated in'dotted'lines. Fig. 2 is a top plan view of my improved plate, the cap being removed andthe'hollow member being indicated in dotted lines. Fig. 3 isa plan view square or rectangular! For purposes'of concrete..1llustrat1on, I

have, in the drawing, shown '--an anchor plate of my invention as a plied for connecting a cap 1 to the end 0 a hollow mem-- her 2, by means of a bolt or screw studl3, all

of. which are indicated in dotted lines.

My improved anchor plate, designated as a whole by the'reference' numeral l, is made of sheet metal, preferably thin sheet'steel,

which will render said plate slightly resil ient. Said plate comprises inclined end poi tion of thestrain to which said anchor plate tions 5 and 6, which diverge in thedirecwill be subjected in use. .As shown, also, said plate comprises a. flat portion '7, inter- I 6 mediate the end portions .5 and 6. For-med on the'end portions 5 and 6,- preferablylat the extreme ends thereof, are projections 8, and .9.wl1ich, in use, are designed and adapted to engage corresponding holes,, -indi cated at 10, in the hollow member. 2.

The over-all'length of the anchor plate ,4:

hollow member.

-5 and 6 ,015 the anchor plate, designated is preferably slightly greater than the diameter of the hollowmember 2, with which it is .to be used, the resilience of'said plates permitting-them to be compressed for the purpose of inserting them into the hollow nielnber 2 and also causing them to expand:

to effect engagement of the projections 8 plate 4 is formed is relatively thin, as

shown in the drawing, thescrew threaded hole'or'opening 11 therein is preferably extended by means of a flange 12 around the same, whichwcan be conveniently formed by b stamping up the metal removed-informing said hole 11.

The ends of the inclined portions 5 and 6 ofthe anchor plate 4- conform substantially to the inside of the hollow memberfl, As

shown in Figs. 1 and'2, the hollow member 2 is round and the inclined ends of the anchor plated are rounded to correspond thereto. As, shown in FigQ l, the hollow member, designated 2 is rectangular and the ends of the inclinedportions, designated 4 are made straight, "so as-to conform to the inside thereof. Instead of the holes 10, my.

invention contemplates the use of any form of lodgmentfor the ends of the'plate 4.

I claim ,1..An anchor plate for connecting a screw-stud, bolt, or the like, into the e'ndof a hollow member, comprisinginclined end portions adapted for engagement withlodgvments on the side walls of said hollow member, and means adapted for connecting a screw-stud, bolt, or the like, to said plate,

said anchor plate being constructed and arranged tobe inserted inside of said hollow member with its inclined end portions diverging in the direction of. the stress-to which said plate will be subjected in use, substantially as described.

.2. An anchor. plate for: connecting a 7 screw-stud, bolt, or the like, into the end of 1 stress to which said plate will besubjected a in use, substantially as described;

4-. An anchor plate for connecting a a hollow member, comprising inclined end portions, projections on said end portions adapted to engage holes formed in the side walls of said hollow member, and means adapted for connecting a screw stud, bolt,-,or the like, to said plate, said anchor, plate be ing constructed and arranged to be inserted inside of said hollow member with its inclined end portions divergingin the direcfor connecting a screwstud,.bolt, or the like,-

to said plate, said anchor plate, being-constructed and arranged tobe inserted inside of said hollow member with-its inclined end. portionsdiverging in the direction of the screw;stud, bolt, or the like, into the end of a hollow'm'ember, comprising inclined end portions and an intermediate plane p01 tion, projections on said inclined end por tions'adapted to engage holes formed in the side. walls of. said hollow member, and means adapted for connecting a screw-stud, bolt, orthe like, to said plate', said anchor platebeing constructed and arranged to be inserted inside of said-hollow member with its inclined end portions diverging in .the' direction oi the stress to which said plate will be subjected-in use, 'substantiallyfas described; V

y 5.- An anchor "plate for connecting a.

screw-stud, bolt, or the like, into the end of tions adaptedrto engage holesformed in the side walls of said hollowmember, said anchor plate being provided with a screw threaded opening adapted for engaging said anchor plate with a screw-stud, bolt, or the like, substantially as described;

In testimony, that I .clann, the foregoing as my invention,- I affix my signature in presence of two subscriblngwitnesses, this 13th day of August, A. D. 1910.
